Apple has finally acknowledged the use of OpenStreetMap data in its iOS iPhoto app, the open-source mapping project said yesterday.

The iPhoto app, a photo-sorting tool for the iPad and iPhone, switched from Google Maps to OpenStreetMap (OSM) data back in March. The app uses mapping data so it can display the shoot location of geotagged photos.

However, the app did not credit the use of OSM data, leaving it up to the mapping project's team to point out the development in a blog post. That post was updated on Thursday with a screenshot of the credits in the latest version of iPhoto, v.1.0.1.
